Infiniti QX50 concept previews production model with variable compression engine

Infiniti revealed its QX50 concept ahead of its official debut at the Detroit Auto Show, and despite the concept title, it looks pretty much production-ready. The company calls the crossover "an evolution of the QX Sport Inspiration" concept, and that's certainly accurate. Side-by-side, the QX Sport, which we already figured was previewing a new QX50, and this concept look nearly identical. The primary changes are bumpers and side skirts that feature the obligatory aluminum trim to look like skid plates, and simple black plastic fender flares. The overall result is a crossover that is pleasant but not exactly exciting that bridges the gap between the small and swoopy QX30 and the large QX60. The plain wrapper hides plenty of impressive technology, though. Under the hood is Infiniti's fascinating variable-compression turbocharged engine. It's a 2.0-liter inline-four that can alter its compression ratio to anything between 8:1 and 14:1. The result is an engine that produces an estimated 268 horsepower and 288 lb-ft of torque. Infiniti says the four-cylinder should be about 27-percent more efficient than a comparable V6. In addition, while the company says this concept just shows a potential application of the engine, it's safe to say that you can expect it in the production model. With the new engine, the QX50 will also switch from to a front-drive platform, with all-wheel drive definitely an option or possibly standard; the current QX50 is based on the aging rear-drive FM platform used on other Infinitis and the Nissan 370Z. The other new tech buried in the QX50 concept's body is what Infiniti calls the "first production-ready incarnation" of its ProPilot semi-autonomous technology. The company doesn't go into great detail about what it will do except for handling stop-and-go highway traffic. We would hazard a guess that the system is functionally the same as the one introduced on the Nissan Serena minivan in Japan. It goes by the same name and can handle stop-and-go traffic, as well as maintain the car's lane position and distance behind other cars. It's another safe bet that we'll see this system in the production model. Other details about the car, such as the interior, have yet to be revealed. We're sure to see it as well as other information about the QX50's technology when it makes its full debut in Detroit. Related Video:

Infiniti Q50S getting G37's hydraulic steering for 2016

Sometimes, new technology doesn't make things better. Take the march of power steering technology as an example. Electrically assisted systems are in vogue at the moment for their ability to increase fuel efficiency, but tuning them to offer good feedback remains something of a dark art. Some automakers get it, but most don't. The previous hydraulically assisted setups just seem to be inherently more communicative when driven with enthusiasm. And it looks like Infiniti might be learning this lesson the hard way.
In talking with Keith St. Clair, the luxury brand's head of product planning, Car and Driver has learned that the Q50S is probably going to ditch its standard electrically assisted steering in favor of a hydraulic system derived from the old G37, a model soon to be renamed the Q40. The system should make the sedan more engaging behind the wheel, but it still won't help those who tick the option box for Infiniti's controversial Direct Adaptive Steering drive-by-wire system.
According to St. Clair, Infiniti's engineers have heard the complaints of critics and previous G37 owners about the Q50S model's electric steering system, and wanted to see what they could do. They didn't have to go far to figure it out - all it required was taking the steering rack off of a G37 and putting it onto the Q50S. After a little tweaking, "the car is a blast to drive," St. Clair reports. Now, the company is said to be fast-tracking the switch, and it could be ready for the 2016 model year.

Race recap: 2015 Abu Dhabi Grand Prix is Germany rising as sun sets

Mercedes-AMG Petronas driver Nico Rosberg Rosberg doesn't attribute anything mystical to the form that got him ahead of teammate Lewis Hamilton. He said simply, "Before it was close in the other direction, now it's close in this direction." Mercedes non-executive chairman Niki Lauda went further, saying Rosberg's "brain has switched." Under the desert spotlights it switched so far ahead that Lewis Hamilton qualified nearly four tenths behind the German. Kimi Raikkonen flew the scarlet for Ferrari in third position. Being three spots ahead of Valtteri Bottas gave Raikkonen a huge advantage in locking up fourth position in the driver's championship. Even if he doesn't care about it, as he's publicly stated, Ferrari probably does. Teammate Sebastian Vettel was classified 16th after the German slowed down after making a mistake on his final hot lap, and neither he nor his engineer realized how quickly times were falling on a cooling track. He'd be promoted to 15th when Lotus driver Romain Grosjean was penalized for a gearbox change. Sergio Perez knocked it out of the park for Sahara Force India, claiming fourth ahead of Daniel Ricciardo in fifth for Infiniti Red Bull Racing. Williams driver Bottas was in sixth, in front of the second Force India of Nico Hulkenberg and the second Williams of Felipe Massa in eighth. Daniil Kvyat ensured both Red Bulls were in the top 10 with his ninth position, and Carlos Sainz got the upper hand in qualifying over his Toro Rosso teammate Max Verstappen for the final time this year, rounding out the top 10. Beyond Nico Rosberg's mind, one of his weaknesses was his slow starts. Those are stronger, too, the German tearing off away from the field when the lights went out. Hamilton bogged enough to have to defend from Perez behind, the Mexican trying to slide between Hamilton and Raikkonen on the run to the first corner. Rosberg held the lead into Turn 1 and likewise held it through Turn 21 on the last lap of the race, only ceding it during pit stops. Rosberg's 14th victory gets him level with Graham Hill on the wins list – on the anniversary of Hill's death in a plane crash – and marks the first time in his 10-year F1 career that he's won three races in a row. More proof of his strength: the last few races we haven't heard Rosberg ask for regular updates about what Hamilton's doing, he just drives. Hamilton gave it his best but that wasn't enough.
